A lawful interception administrative function, LI ADMF, () in a telecommunication network () obtains from a quantum key distribution network, QKDN, () a quantum key and a key stream identifier, KSID, associated with the quantum key. The LI ADMF () transmits the KSID associated with the quantum key to an LI entity () in the telecommunication network (). The LI entity () then obtains, from the QKDN (), a quantum key associated with the KSID transmitted by the LI ADMF (). Such a procedure provides a secure exchange of quantum keys to enable encryption of sensitive data within messages exchanged by LI entities in the telecommunication network ().

Method in a telecommunication network, and computer system

A method is described for access to a directory by an application (). A function library () handles a first request from the application for fetching the information from a server. The first request is forwarded from the function library () to the server by a client module (). A request identifier () is sent from the function library to the application when the first request is forwarded to the server. A response signal () to the first request is sent from the server and received by the application. The response signal comprises a response identifier. The response identifier is checked to match the response signal () to the first request. A function from the function library is called () by the application for decoding the response signal. The decoded response signal is returned () from the function library to the application. A device and a program are also described.

Method and device for access to a directory

An analog-to-digital converter based on the Bernoulli map's iterative principle, made by discrete, hybrid, mixed components, or on an integrated circuit, utilizes a single main loop circuit in which the analog signal cycles N times.
